Earth Hour 2011

• On March 29, one day after Earth Hour 2009, Dân Trí daily newspaper published an article about the other side of Earth Hour. It was concerned that many young people chose to drive around the darkened cities for fun, exhausting petroleum instead of electricity and resulting in long-time traffic jams.
• During the 2010 Earth Hour in the city of Uusikaupunki in Finland, a 17-year-old female motorcyclist hit a 71-year-old man, who was walking on the street instead of the sidewalk for an unknown reason. The man died from his injuries, while the motorcyclist and her passenger were uninjured. At the time of the accident the street lights had been turned off as part of the Earth Hour. The police stated that the lack of street lighting may have played a part in the accident, while the mayor believed the city's street lights would have been too dim to prevent it.
• Jeremy Clarkson, host of the BBC motoring programme Top Gear, confessed to switching on all electrical items in his home as a protest against the perceived impact of Earth Hour, claiming the event would have little to no effect on attitudes towards climate change.
